Answer:
y = 2x -8
Step-by-step explanation:
Answer: Close. Your observation is correct. When you see that the difference between two numbers in the sequence is a perfect square, you are looking at a pyramidal sequence
1² = <u>1 </u> top of pyramid
1 + 2² = <u>5</u> total in top 2 layers
1 + 2² + 3² = <u>14</u> total in top 3 layers
1 + 2² + 3² + 4² = <u>30</u> total in the top 4 layers.
1 + 2² + 3² + 4² + 5² = <u>55</u> total in the top 5 layers.
Layer 6 is 6² more, 91
Layer 7 is 7² more so, 140
I think you got it.
Step-by-step explanation: The numbers are like when you keep adding the layers in a pyramid, and the next number is the total of the previous layers plus the square of the next layer number.
Answer: C
<u>Step-by-step explanation:</u>
f(x) = 26.2 - 0.1x
f(100) = 26.2 - 0.1(100)
= 26.2 = 10.0
= 16.2
f(5-) = 26.2 - 0.1(50)
= 26.2 - 5.0
= 21.2

Answer: D
<u>Step-by-step explanation:</u>
f(x) = 2|x - 3| + 1
2 units right: f(x) = 2|x - (3 + 2)| + 1
= 2|x - 5| + 1
I can not explain how but it is 100 gallons in 20 minutes
The number of seats in each row is an illustration of mathematical expressions.
- <em>The numerical expression for the number of seats in each row is: </em>
<em /> - <em>The number of seats in each row would be 6</em>
The given parameters are:
So, the remaining seat is calculated as:
Substitute known values
The number of seat in each row is calculated as:
Substitute known values
Hence, the numerical expression for the number of seats in each row is:
When the expression is solved, the number of seats in each row would be 6
